Security analyzing and designing GUI with the resources model

Recently security problems in the Graphic User Interface (GUI) of applications have become a serious threat for system security. Because much of security experts don't design the GUI from end user's point of view, users have problems to practice security. The aim of Human & Computer Interaction (HCI) and Security (HCI-Sec) is to improve the usability of security features in end user applications. In this paper we apply the resources model (a model in HCI) to analyzing and designing system GUI with a security perspective to achieve a more secure and usable system. We studied Tests part of E-learning system in Ferdowsi University of Mashhad (FUM) as our case study. And we exploited faults that slow down user co-ordination with the system and used this model to explore design alternative. We generally analyzed GUI and proposed an alternative GUI in order to solve interaction problems. Finally we analyzed the GUI with a security perspective to improve the usability of security issues in this system. The results show this model works very well in the field of security.
